八路缓冲器/驱动器，具有三态输出 OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS

The is an octal Buffer/Driver with 3-state outputs and is designed for 1.65 to 3.6V VCC operation. This device is organized as two 4-bit line drivers with separate output-enable OE inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. The outputs, which are designed to sink up to 12mA, include equivalent 26R resistors to reduce overshoot and undershoot.
